CPLD在DSP多分辨率图像采集系统中的应用

Application of CPLD in Multi-resolution Image Gathering System Based on DSP

基于嵌入式系统中对图像实时采集的需要,设计了一种以CPLD和DSP器件为核心的多分辨率图像采集处理系统,提出一种由CPLD控制图像的行、场信号延时,奇偶数据分离存储来得到不同分辨率的图像数据的方法。全文分别就数据采集的逻辑功能设计;总线逻辑切换设计;CPLD逻辑功能仿真验证等进行了详细介绍。

Based on the need for real-time image gathering in embedded system, this paper designs a Multi-resolution image gathering and processing system based on CPLD and DSP devices. This paper put forwards a method that vertical and horizontal signal delayed, odd and even data separately stored are controlled by CPLD so that different resolution images are generated. This paper also introduces logic functional design of data gathering; design of logic bus switching and CPLD software realization etc. in detail.
